Flow prototype
Frame flow prototype around repeated mobile tasks, platform context and the states users encounter outside the happy path.
← Mobile & Product Experience
PRODUCT / EXPERIENCE / SERVICE
Make risky product assumptions tangible before engineering cost multiplies.
Make critical product assumptions tangible early so teams can test flows, states and interaction logic before full engineering expands.

WHERE THIS EARNS ITS PLACE
Start with the repeated mobile task, not the screen count.
This is most useful when the current situation involves a product concept where the riskiest interaction or workflow is still uncertain.
We work from real usage context, interruptions, platform conventions and state changes so the product remains understandable outside ideal happy-path screens.
ENGAGEMENT SCOPE
What Prototyping should cover in practice.
The scope should connect mobile journeys, interaction states, platform behavior, engineering constraints and release readiness into one product decision.
State modelling
Prototype state modelling across loading, error, empty and interruption states before visual polish hides interaction problems.
Usability testing
Implement usability testing with platform conventions, maintainable components and realistic device constraints.
Decision capture
Verify decision capture on representative devices and release conditions, then feed findings back into the product.
DELIVERY MODEL
Design for real device behavior before polishing ideal-state screens.
Mobile work moves from repeated user tasks into state-aware interaction, device-conscious engineering and release validation across the conditions people actually encounter.
- 01Journey definition
Clarify the repeated task, user context, device constraints and business outcome before expanding the screen inventory.
- 02Flow & prototype
Prototype loading, empty, error, interruption and permission states alongside the primary journey so the experience remains coherent.
- 03System design
Engineer with platform conventions, maintainable components, backend realities and representative device performance in view.
- 04Build & release
Validate on real devices and release conditions, then use product and stability signals to guide the next iteration.
A GOOD FIT WHEN
There is a clear reason to invest in Prototyping.
- There is a repeated mobile task or product behavior worth improving.
- Platform behavior, device constraints and release quality matter to the outcome.
- You want product decisions that can survive beyond the first screen set.
RETHINK THE SCOPE WHEN
The brief needs reframing before Prototyping is the answer.
- The brief is only a list of screens with no clear user journey or product behavior.
- The mobile experience is expected to copy desktop interactions without adapting to device context.
- Release, backend, accessibility or state behavior are being treated as afterthoughts.
FAQ
Questions worth answering before Prototyping starts.
Scope and commercial details are finalized against the actual context, dependencies and release expectations rather than hidden behind a generic package.
When is Prototyping the right fit?+
This is most useful when the current situation involves a product concept where the riskiest interaction or workflow is still uncertain. The first conversation should clarify the current constraints, the desired outcome and what would make the engagement worthwhile.
Can this improve an existing app instead of starting over?+
Yes. We can begin with a live product, identify the journeys and technical areas causing the most friction, and preserve stable behavior where a rewrite would add risk without clear value.
How do you decide between native and cross-platform delivery?+
The decision depends on product requirements, platform-specific behavior, integrations, team constraints and the amount of code reuse that is genuinely useful. We do not treat one approach as universally correct.
How do you handle device and release quality?+
Representative device testing, realistic app states, performance checks and store-release requirements are considered as part of delivery rather than a final checklist after engineering is complete.
START WITH THE CONTEXT
Bring the user journey, platform and release context.
Share what users need to accomplish repeatedly, where the current experience breaks down and any device, backend or store constraints already known. We can then determine whether Prototyping is the right starting point.
